i got an old mobo, asus p5vd2-vm, i wanted to upgrade it(atleast).
what vcard can u suggest for me buy for this mobo? coz i bought a a sapphire HD 7850, no display.
so i think this is because of chipset limitation. and it can cause to bottleneck too.
so im planning to buy a new vcard for my old mobo so that it will work fine and can play games like NFS, FIFA 13, NBA 2k13 and online games.

some references :
CPU-Upgrade: ASUS P5VD2-VM processor support and specifications
ASUS - Motherboards- ASUS P5VD2-VM

pls help me....
